77@'371/655566?, I -Iwfuerr/ZTO 7' mit (tira-Q may IMPROVE!)DUMPING-PLATFORM The Schedule referred to in these Letters Patent yandmaking peut of the same.

To all whom it lmay/y concern:

- Be it known that I, SAMUEL OfKnNAGA, of the .cityof Kankakee, in thecounty of Kankakee, and State of Illinois, have invented a new anduseful maf chine for dumping wagons or cars of their contents,andlknownas S. O. Kenagas Dumping-Platform; and I do hereby declare thatthe following is a full, clear, and exact description ofthe constructionand operation of the same, reference being had to the annlredrawings,making a part of this specification, in w c Figure 1 is a verticalVlongitudinal section through the middle of the machine, and

Figure 2 is a horizontal view, with the Vtrap-door raised and the doorbroken away at places to show its construction underneath.

Similar letters refer to like parts.

A areposts fonsnppcrtnfiloor.

B is floor.

O, the dumping-platform.

D, the axle.

E, bearings.

V G', caps.

1I, upright posts for support of lever. J, braces.

lever.

Ii, a lfulcrum.

M, dogs.

O, levers to the dogs M.

P, slots in iioor.

Q, trap-door.

R, bevel ends of joistsin trap-door.

I", bevel ends in oo'r-jo'ist to dumping-platform.

S, shaft to lever.

s', anti- 'iction roller.

T, spout.

t', bin.

U, contents of wagon.

V, wagon dumping itsy load.

" p', has'pto. fasten the shaft.

X, rods to hold the wagon on the platform.

Y, eye-bolts to fasten the rods to the platform.

y', rings to pass on the hubs. p

d, hinges to trap-door.

A A are posts supporting the iiooring B B, in which the dumping-platformC is cut or tted.

D is the axle on which the platform is suspended, and issupported by thebearings E E in the caps F F of the posts G G.

I I are upright posts. They are firmly held by the braces J J, and forma support for the lever K, on its fulcrum, L. v

N is a cross-piece framed into the posts I I, and also into the postAthat supports the door. It tends to stiien the-posts I I, and forms arestfor the dogs M M,^which are attached to it by hinges at the feet ofthem, and their upper ends made to swing to and from the under edgeofthe platform VC at c', by means -of the levers 0 0, which 'passthrough the slots P P to the iioor above.

Q is a trap-door, hung onhinges at q q, and made to cover the openingover the spout T; The ends of the joist forming the door are bevelled,R, and made to lap on .the bevel ends r of the floor-joists in theplatform C.

' S is a shaft connected with the long sweep of .the lever K. It has aT-head, and passes up through the oor a distance equal to the sweepofthe long arm of the lever K, in its depressing the rear end of theplatffor'm. to its required inclination.A Upon returning the platform toa level with the floor, the shaft draws down so as to bring the T-headeven with the docu-where it irs-covered with-a liasp,lpfrmlyl;fastened.in the fluor, p

and transmits, through the lever K, Aa firm support for the platform torest upon. i

S is an anti-friction roller, bedded in the centreoi` -the rear end ofthe platform, for the lever K to bear against. t

T is a spout to conduct the contents Uof the wagon V to the bin t. p

X X are iron rods linked to the eye-bolts Y Y.l They are firmly boltedto the platform O, at the opposite end of the rods. Rings y are attachedso as to press on the hubs of the two hind wheels, and prevent the wagonfrom backing on the .platform when in position for discharging its load.

In iig. l, the rear end of the platform isrepresented asA beingdepressed, and its front end elevated, so as to produce an inclinationsufficient for a wagon standing on it to be discharged Vof its contentsby its own r gravity. This inclination of the platform G is con` trolledby the shaft S which is connected with the level` K. When the platformis not in use, it lies level with the iioorB B. The trap-door Q isclosed on the end of the platform, and the dogs M M are thrown over bymeans of their levers O 0, so as to catch under the end of the platform,and hold it firmly in position, independent of thelever K, which might,:from a `v cause, become loose through imperfections or neglef, infastening the shaft S. p

. The .most particular adaptation of this machine ig at warehouses,where grain is received by wagon-loans in bulk, and required to beshovelled into hoppers or bins constructed to receive it. In cases whereware houses are constructed on a suilciently high location, as the bankalong a canal, or on the surface where 'a railroad is constructedthrough deep cuts, and no mae chinery required for elevating the grain,the dumpingplatform may be constructed alongside of such ware-v house,at a suiiicient elevation to spout the grain to any part of theWarehoues required, and reached by means of constructing a drive-way ofsuch inclination as will admit of a loaded wagon being driven up to it.In cases Where warehouses are constructed on a level with the means ofshipment, as a canal-boat or railroad-car, and machinery is used forelevating and conveydng grain sufiicient to spout into the canal-boat orcar, the dumping-platform may be constructed alongside of the warehouse,by means of a pit dug of such depth and size as will admit of itsWorking, and spouting the grain into a hopper, from whence it isconveyed oielevated to the bins or place of storage required.

What I claim as my invention, and desire to secure byLetters Patent, is-

Tlie arrangement and construction of the door B, dumping-platibrm Crrods X, and hub-rings y','leve1 K, shaft- S, hasp 1)', dogs M, lever O,and trap-door Q, in combination with posts A, G, and I, axle D, caps F,friction-roller S, fulcrum L, rest N, spout T, and bin t', substantiallyin the manner and for the purposes herein shown and described.
